How can I effectively use advanced types in TypeScript?

Advanced types in TypeScript include features like union types, intersection types, and mapped types. What specific use case do you have in mind?

I'm trying to create a function that accepts multiple types of inputs.

You can use union types for that. For example, you can define a function like this: function example(input: string | number) { ... }.

What about using intersection types?

Intersection types allow you to combine multiple types into one. For instance, type A = { x: number }; type B = { y: string }; type C = A & B; creates a type with both properties.

Can you give me an example of a mapped type?

Sure! A mapped type allows you to create new types by transforming properties of an existing type. For example: type Readonly<T> = { readonly [K in keyof T]: T[K] }; makes all properties of T readonly.
